As I play the barbarian in D3, I start to think that whirlwind- aka the spin attack- shouldn't have to use fury, it seems like a normal attack that the barbarian would have as a primary, mainly to me because of the fact that you are literally spinning yourself, and not using anything like a magic hammer (hammer of the ancients), or something like rend. It doesn't seem to look like a secondary, seeing as most of them visually look like they use fury, and to me it doesn't seem like it needs fury in general! What do you guys think? I think that if in D4, they make it a little bit less powerful, it could be a primary!
